DOMDocument->registerNodeClass()  -- Register extended class used to create base node type

Описание

class DOMDocument {

bool registerNodeClass ( string baseclass string extendedclass )

}

This method allows you to register your own extended DOM class to be used afterward by the PHP DOM extension.

This method is not part of the DOM standard.

Параметри

baseclass

The DOM class that you want to extend. You can find a list of these classes in the chapter introduction.

Of course, you won't be able to register a class extending DOMDocument but you can always start your document by instanciating your own extending class.

extendedclass

Your extended class name. If NULL is provided, any previously registered class extending baseclass will be removed.

Връщани стойности

Връща TRUE при успех или FALSE при неуспех.

Примери

Пример 1. Adding a new method to DOMElement to ease our code

<?php

class myElement extends DOMElement {
   function appendElement($name) { 
      return $this->appendChild(new myElement($name));
   }
}

class myDocument extends DOMDocument {
   function setRoot($name) { 
      return $this->appendChild(new myElement($name));
   }
}

$doc = new myDocument();
$doc->registerNodeClass('DOMElement', 'myElement');

// From now on, adding an element to another costs only one method call ! 
$root = $doc->setRoot('root');
$child = $root->appendElement('child');
$child->setAttribute('foo', 'bar');

echo $doc->saveXML();

?>

Примерът по-горе ще изведе:

<?xml version="1.0"?>
<root><child foo="bar"/></root>
